    • 1. VMware ESX Server Datacenter-Class Virtual Infrastructure for Mission-Critical Environments Copyright © 2005 VMware, Inc. All rights reserved.
    • 2. VMware Mission Transform industry standard server and desktop computing through virtualization 70% Reduction in Operating Costs Application Application App App 40% Reduction in Hardware and OS OS OS Software Costs OS Increased Reliability Virtualization & Responsiveness Greatly Enhanced Hardware Hardware Hardware Business Continuity Increased Utilization & Return on Assets Copyright © 2005 VMware, Inc. All rights reserved.
    • 3. What is Virtual Infrastructure? Infrastructure is what connects resources to your business Virtual infrastructure is a dynamic mapping of your resources to your business Result: decreased costs and increased efficiencies and responsiveness VMware technology provides a thin virtualization layer that encapsulates operating systems and applications into portable virtual machines Copyright © 2005 VMware, Inc. All rights reserved.
    • 4. What is Virtualization? Without Virtualization With Virtualization Application Operating System Hardware • VMware provides hardware virtualization that presents a complete x86 platform to the virtual machine • Allows multiple applications to run in isolation within virtual machines on the same physical machine • Virtualization provides direct access to the hardware resources to give you much greater performance than software emulation Copyright © 2005 VMware, Inc. All rights reserved.
    • 5. Three Key Properties of Virtualization Copyright © 2005 VMware, Inc. All rights reserved.
    • 6. Three Key Properties of Virtualization Partitioning Isolation Encapsulation • Run multiple operating • Isolate faults and security at • Encapsulate the entire state systems on one physical the hardware level of the virtual machine in machine • Dynamically control CPU, hardware-independent files • Fully utilize server resources memory, disk and network • Save the virtual machine state • Support high availability as resources per virtual as a snapshot in time shared data is cluster-ready machine • Re-use or transfer whole virtual for failover and redundancy • Guarantee service levels machines with a simple file copy Copyright © 2005 VMware, Inc. All rights reserved.
    • 7. VMware ESX Server Datacenter-Class • ESX Server is a virtual Virtual Infrastructure machine platform with a for Mission-Critical Environments bare-metal architecture for highest possible performance • Lean virtualization-centric VMkernel delivers complete control over hardware resources • Supports dynamic allocation of computing resources • Highly available, fault-tolerant and secure design • Supports both scale-up and scale-out strategies Copyright © 2005 VMware, Inc. All rights reserved.
    • 8. Bare-Metal vs. Hosted Virtualization Hosted (Workstation, ACE & GSX Server) Bare Metal (ESX Server) • Device support is inherited from host • Maximum performance with lowest overhead using operating system for maximum hardware certified hardware compatibility • Highly efficient direct I/O pass-through architecture • Virtualization installs like an application for network and disk rather than like an operating system • Highly secure micro-kernel virtualization layer— • Can run alongside conventional only 100Ks of lines of code versus 10–25 million applications lines of host operating system code • Advanced features like VMotion available Copyright © 2005 VMware, Inc. All rights reserved.
    • 9. ESX Server Components • VMkernel • Manages all virtual machines • Service console • Linux-based bootstrap manager VMkernel and administrative interface • VMware management interface (MUI) • Access to ESX Server admin • ESX Server remote console • Access to virtual machines • VMware Scripting API • Automate management & Shared SAN VMware Management Interface (MUI) monitoring Storage & Remote Console Copyright © 2005 VMware, Inc. All rights reserved.
    • 10. ESX Server Remote Management Features • Web-based management interface • Create, modify, stop, start, suspend/resume virtual machines • Monitor CPU and memory usage • Access from any browser • Remote console • Windows and Linux versions • Create, configure & manage VMs • Full mouse and keyboard support • Remote full screen • Tabbed “quick switch” interface • Good low-bandwidth performance • SSL security Copyright © 2005 VMware, Inc. All rights reserved.
    • 11. ESX Server is a Resource Multiplier with Very Granular Resource Management Resource Physical Server Virtualization CPU 4-Way Server 20–30 VMs Memory 6GB Server 12GB VM Memory Storage 2 HBAs (paired) 32 Virtual Disks Network 2 NICs (teamed) 16 Virtual NICs • All physical resources are shared by virtual machines resulting in a multiplier effect • The goal is to maximize hardware utilization for greatest ROI while providing isolation • ESX Server provides very granular resource allocation per virtual machine • Can establish minimum, maximum, and proportional share amounts per VM for CPU, memory, disk and network bandwidth and modify these allocations while they are running • Allows apps to use greater resources periodically without requiring a constant allocation Copyright © 2005 VMware, Inc. All rights reserved.
    • 12. VMware Virtual SMP • Add-on module for ESX Server • Allows single virtual machine to span two processors • Benefits • Increased virtual machine performance • Move more intensive workloads into virtual machines • Meet requirements of applications designed for 2-way systems • Develop and test applications in dual processor environments • Compatible with dual-core and hyperthreaded processors Copyright © 2005 VMware, Inc. All rights reserved.
    • 13. Device Management for Hardware Virtualization 1-4 Ports 1-4 Ports Up to 2 CD-ROMs 1-2 Drives • VMkernel virtualizes the physical hardware and presents each virtual machine with a standardized virtual device • This standardization makes virtual machines uniform and 1-4 Ethernet Adapters portable across 1-4 SCSI Adapters platforms 1-15 Devices Each Up to 3.6GB RAM and 1 CPU or 2 CPUs with VMware Virtual SMP Copyright © 2005 VMware, Inc. All rights reserved.
    • 14. Network Management for Network Virtualization • VMs use virtual NICs mapped to one or more physical NICs through virtual switches • Each virtual NIC gets its own MAC address • Zero collisions occur for internal traffic • NIC Teaming groups 2-10 physical NICs to form a highly redundant network device • Statically load-balances traffic for all VMs • Traffic shaping can manage bandwidth per VM • Failover is offered transparently to all VMs • Extra Security available for virtual NICs • VMs on the same virtual switch cannot see each other’s traffic • Disallow MAC address changes by the OS Teamed Physical NICs • Disallow forged source MAC transmits • Disallow promiscuous mode Copyright © 2005 VMware, Inc. All rights reserved.
    • 15. Access Management ESX Roles Allow Granular Management Control • ESX Server allows for four levels of privilege to control access to ESX Servers and their virtual machines • VirtualCenter extends the ESX Server access control by allowing staff to manage all ESX Servers from a central point with active directory domain integration Copyright © 2005 VMware, Inc. All rights reserved.
    • 16. ESX Server Hardware Support Rack and Blade • Dell • NEC • Fujitsu Siemens Servers • HP • Unisys • IBM • Bull • Intel white box compatible servers and blades Storage Area • Dell • HP • NEC Networks • EMC • IBM • 3PAR • Fujitsu Siemens • Network Appliance SCSI Controllers • Adaptec • LSI Logic RAID Controllers • Adaptec • HP • LSI Logic • Dell • IBM • Mylex Fibre Channel • Emulex Adapters • QLogic Ethernet NICs • Intel • 3Com • Broadcom Copyright © 2005 VMware, Inc.
